Why should I change my battery?Car batteries wear out over time, and extremely hot or cold weather can speed up a good battery’s demise. That’s because your battery converts chemical energy into electricity using the anode, cathode, and electrolyte. Damage to any of these three parts can prevent it from working correctly.

The cathode and anode are the respective positively and negatively charged sides of the battery, and the electrolyte is a buffer between the two. The chemical reactions inside cause a buildup of electrons in the anode. Just like magnets, these similarly charged particles repel one another, but are blocked from moving to the other side of the battery by the electrolyte. That means that negatively charged particles need to travel through something external to the battery to circumvent the electrolyte and reach the cathode, where particles carry a positive charge.

That’s where your car comes in. Your vehicle’s electrical system provides a path for electrons to travel when the positive and negative terminals are hooked up, and this travel provides electrical current to your vehicle.

How long does a battery last?Most batteries last 3-5 years. If your battery is 4 years old or older, your car or truck battery is at risk. If you’re worried, AutoZone offers free battery testing and charging service to check out your current battery. We'll even take care of the old one with battery recycling.
